Declaration and Access Control Choose the correct statementpublic class Circle{ private double radius; public Circle(double radius){ radius = radius; }} The program will compile, but we cannot create an object of Circle with a specified radius. The object will always have radius 0. The program has a compilation error because we cannot assign radius to radius. The program has a compilation error because it does not have a main method. The program does not compile because Circle does not have a default constructor. The program will compile, but we cannot create an object of Circle with a specified radius.
